But Australian researchers found that by using antibodies against MIC1 they were able to switch appetite back on. When normal and obese mice were treated with MIC1, they ate less and lost a lot of weight, suggesting that MIC1 may also be used to treat severe obesity, the Sydney researchers said in a statement yesterday.“This work has given us a better understanding of the part of the brain that regulates appetite，” said Herbert Herzog, director of neuroscience research at the Garvan Institute in Sydney. “Our bodies send complex chemical signals to our brains, which interpret them and send back orders: in this case, eat or dont eat. Our research indicated that MIC1 is a previously unrecognized molecule sending a donteat signal to the brain，” Herzog said.The researchers said it was hoped that in the near future, the MIC1 findings will prevent many advanced cancer patients from “wasting away (消瘦)”Sam Breit, who originally cloned the MIC1 gene, said he believed the findings could havea significant impacton a range of appetiterelated disorders. “Injecting mice with MIC1 protein also made them stop eating, suggesting that it may be possible to use this to advantage for treating patients with severe obesity，” he said.The MIC1 findings were published in the latest NatureMedicine magazine and the team of researchers led by St Vincents Hospital in Sydney hope to develop a human antibody and run clinical trials in the next few years.1According to the text, MIC1 _. Ais produced by cancers of some special type Bcan target receptors in the brain that switch on and off appetite Cproves effective on mice in making them healthier Dis a molecule that sends a donteat signal to the brain答案：D细节理解题。由文章第三段最后一句可知D正确。第二段第一句可知MIC1是由普通的癌所产生的，选项A错在special type，应为common cancers；由第二段可知，MIC1的目标受体是大脑内switch off appetite的受体，因此B错误。由倒数第二段中的“Injecting mice with MIC1 protein also made them stop eating”可知C错误。2We can learn from the text that _.Athe researchers now understand better the part of the brain controlling appetiteBthe MIC1 findings have already been put into clinical useCMIC1 will surely be used to cure patients of serious obesityDthe researchers originally cloned the MIC1 gene to treat cancer答案：A细节理解题。由文章第三段第一句可知A正确，即这项发现使得科学家们对于大脑中控制食欲的部分有了更好的了解。3What cannot we conclude from the passage? AThe researchers hoped the findings would be applied to treating human diseases soon. BThe researchers hoped the findings would be used to cure cancer patients. CSam Breit believed the findings could be useful in treating appetiterelated disorders. DClinical trials havent been run yet.答案：B推理判断题。根据文章可知MIC1可以调节极度消瘦或肥胖的人的食欲，因而控制他们的体重，并没有谈到它对癌症的治疗作用。4What can be the best title for the text? AA discovery to cure cancer BResearchers find hunger switch to control appetite CMIC1, a molecule to control appetite DAustralian scientists find a way to clone MIC1答案：B标题判断题。文中多次出现的关键词是findings (发现)，而文章主要讲的也是关于MIC1的发现，以及它可能带来的控制人们食欲的好处。同时结合文章主旨段落第一段可知B为最佳标题。1obese adj. 肥胖的2.antibody n. 抗体3interpret v. 解释；翻译have an impact on 对有影响B Almost every day, we discuss the topic of health, especially for kids. But what is health? “Health” means eating well, getting enough exercise, and having a healthy weight. Lets read the following rules. They can help you stay healthy.Eat a_variety_of foods, especially fruit and vegetables. We all know that eating fruit and vegetables can help us stay healthy, but many of us only eat our favorite foods. Remember that we can only get the nutrition we need by eating different kinds of food, especially fruit and vegetables.Drink water and milk most often. Everyone knows that water is important. Besides that, kids need plentyof calcium (钙) to grow strong bones, and milk has a lot of it. Every day, you should drink at least three cups of milk (1300 milligrams of calcium), when you are 9 years old or older. You should also try to have less sugary drinks, like soda and coca. They include a lot of sugar. Sugar just includes calories, not important nutrition.Listen to your body. When you are eating, notice how your body feels. When your stomach feels comfortably full, stop eating. Eating too much makes you feel uncomfortable. If you do it too often, it can make you unhealthy and fat.Limit screen time. Whats screen time? Its the amount of time you spend watching TV, movies, and playing computer games. The more time you spend on these sittingdown activities, the less time you spend playing sports, like basketball, and doing other activities like bike riding and swimming. Try to spend no more than 2 hours a day using scr
